The transfer devices for 'carrying the .tens ,from counters of lower denomination to, those of next higher denon'iination comprise rocking -levers or carrieis 610 journaledon a cross rod (300. Pawls 611 pivoted at 651 to thchfront rocker arms normally engage the, ratchets 410 oi the counters 490 prevent over-rotation thereof, Studs 361 3/4 on the'drivc members 310 hold the pawls in effective position against the tension of the springs682 which displace the pawls when the drive members advance, to permit rotation of the counters.

Lugs 610 on the front rocker arms nor mally rest upon projections or seats 635 mounted on trigger's'612- journaled at their lower ends on a cross rod 600, to retain the rockers in their normally set 'or cocked positions againstthe tensions ofthe carrying pivoted at 650 to the rear rocker arms.

When the capacity of a counter is about to be.exceeded, that is, when the counter .is being .turned from 9 to 0, 1t presses a cam 411 thereon against the free end of its associated trigger to rockthe latter against the tensionof a restoring spring 681 and release the rocker 610 to the action of the carrying spring, which rocks 'thefront arm of the carrier downwardly to displace the over rotation preventer pawl 611 and, engages the carrying pawl 610 1/2 with the ratchet 410 of the next counter tothe left, to turn the counter forwardly, A tooth 610 ,on vthe rear rocker arm engages between the teeth of the ratchet to limit the rotation impart- -ed thereto by the carrying pawl to one -40 step. a

The foregoing construction is old and only constitutes part of the present invention in so far as it, is combined with the novel features hereinafter set fortln 1 In machines, which employ transfer'or c'arryin A mechanisms operable independently o the counter drive members, of which the VVales is a notable example, the actual addition of ones to the counteis to theleft. of those whose capcities havebeen exceeded, takes place bile \the counters and .drive memlxu's are disengaged.

I urtherlnore, it has been the cnstonrto. complete the direct accumulation of amounts on the counters as early as practicable on the return stroke so as to leave as much time as possiblcduring the latter portion of such return stroke, within which to effect the carry, and then. to reset the transfer mechanism atthebeginning of the next forward. stroke, (w'hlch commences a secondoperation,) in leadmcss for a. posmhle further' earl l on the succeeding return stroke wjneh completes such second operation).

The return of the transfer resettingmcchsubstantially in normal disengaged anisln' tonormal idle position was coincident with the return of the main drive shaft, and since the normally set transfer devices could be tripped by the counters at any timedur ing the retirement of the drive members,

'the transfer devices could follow the returning' resetting mechanism and cage e their .fl

carrying pawls (ill) 1/2 with the rate lets 4:10; prior to thedisengagement of the counters -and drive members, although the actual'roengaged their detcnts 414'. a a w This style of carry was known to 'the'trade between adjacent counters.

ing swiftlywith its full strength to ,efl f'ect the transfer. a

If as counters g ste'r 9999.99 for a. "1 ample, simian-amount, as 9, .is; added to- 4 the units counterflth transfer from the units toLthe, tens counter would, heretofore,

have been of the sheath variet and would take place, during the returnstroke just as the main shaft was approaching the end of its .travel, while the transfer between the tens and hundreds counters, and so on, would be of the snap variety and in rapidly sue eesslve operations, might take place after the main drive shaft had. reached its normal position. Thus, rather nice adjustments were rnecessary, to enable the carrying pawls to properly engage the ratchets 410 when the counters werejn at least two positions, and in one of whichv the counters and'ratchets .were shifting bodily'relatively to the carrying pawls. a k

By shifting tlie limits between which a carry or transfer operation is permittednto take/place, I haveextended or prolonged ters are completely disengaged from their drive members, and have deferred the ac tuationof the transferresetting means from the bcginningto the end of th'evforward stroke, thus eliminating sneak carries and the time witliin jwhich a carry can occur, F

- rod travel in the slots 615 prolon'ging or extending the time within which snap carries may take place. V

Although I-have chosen to illustrate the invention as applied to the Wales form of carrying mechanism, it is obvious that the broad features of my invention are not restricted thereto.

The fornr of transfer resetting mechanisin illustrated, comprises bellcrank 1evers (515 1/2 (Figs. 1 and 2) journaledon a 5 cross rod 508 1/2. Posts'615 1/2"projecting upwardly from the arms 615'1/2 of the levers, support a universal resetting rod 605 which passes through slots 613 in connecting links (313 pivoted at (350 to the rear arms of the several carriers or rockers 610. Springs 384 normally hold the bell crank levers 015 1/2 and the resetting'rod 605 in .levers and having slots (S15 3/; in which the 'trip rod 303travels, the path of travel of the rod being longer than the slots in the actuating links.- Rolls 636 (Fig. 2) on the 3/4; to reduce the friction. e

. Assume that there is an amount registered on the countersand that the 9 key 190 (Fig. 2) has been depressed to Project its stop 115 into the path of its corresponding rack or drive member 310.

Turning the drive shaft 200 forwardly enables the rack to advance as above explained until arrested by its stop.

Meanwhile the draft bars 214 swing the trip .rod 303 forwardly, which ro'd, aften lowering the counters 490 until they. are

supported by the legs"316 on rests958 1/2,

' travels idly in the slots 321 of. the trip .links 321 and 15 3/4 of the actuating links racks having advanced to their proper po-.

sitions, the trip rod first engages the fol-war ends of the slots in the actuating links 6153/4 toadvance the links and rock the resetting levers 015 1/2 which in turn, draw the resetting rod (305 downwardly.

If, on the previous return stroke of-the -drive shaft, a transfer: device has been tripped to effect a carry, the corresponding connecting link 613 will have been raised by the action of the rocker (310 until the lower end wall of its slot (313 strikes against the nornially idle-resetting rod 605-, as

shown in Fig. 4. Consequently, .when the As the maindrive shaft a proaches the end of its forwardstroke, t e

transfer devices as have been tripped?- rod 605 is lowered, as in Fig. .2, -it pulls the tripped connecting link613 with it to witlidraw the carr ing pawl 610 1/2 from the ratchet-410 and elevate the front arm of the rocker until its 1ug'610 clears the projec tion'635 on the trigger 612, whereupon'thef spring 681 snaps the trigger back into place to position the projection beneath the lug- (310. Stops 612' on the triggersstrike a" stationary part, as the rod 600,'tolimit'tl 1el springimpelled travel of the triggers, When the free ends of the. triggers lie in the paths; of the tripping cams 411 (Fig. .1). The resetting rod 605 (Fig. 2) rocks the forward arms of the carriers .610 post their normally reset positions to insure the return of the triggers.

if no transfer devices have been tripped on the previousreturn stroke the resettm rod (305 at the end of its resetting travefi will contact'the lower :end walls of the slots in the connecting links to slightly raise the a forward ends of'the carriers, (Fig. 2-).

The drive shaft 200, through the trip 'rod 303', effects the engagement 'of 'the counters and drivemembers just as the resetting rod .60? reaches the lower ends ofthe slots 6 of those transfer devices which remain in set msitiom'andhaS substantially reset such The space (Fig: 1') I left between the re setting rod when-at rest and the bottoms of the slots in links 913; of the setor cocked transfer-devicesis sufiicicnt,to permit an effective ,0 ieration 'of {the carrying pawl 1 10 1/2 um er-the influence-of, its carrying spring 80 before the-links 613 strike the resettingrml; but on its effective travel downwardtv, the resetting rod rogressi vely reduces this space until it final y passes the point where an eflective carry can "be had even if the ;transfer devices were tri ped.

Obviously; therefore, any, incomplete earries from'the previous return stroke must he completed heforefthe resettin rod reaches this' pbintJ'aS the resetting roc from.

the keepers 615' 1/2 engage shoulders 6 throw-yhy springs 38l connected with the levers 615.'1/2,,but as the resetting levers are.

. counters and drive members, it would bethe latches which hold the levers and the resett'in rod in idle position against overrocked by the advance of their actuating links 615 3/4 at the end of the forward stroke of the main shaft, the keepers 615 1/2" swing away from..the shoulders 616* and free the latches to the action of the springs 384 (con veniently. connecting the latches and resetting levers) which-snap the shoulders 616' over the keepers to prevent the restoration of the resetting levers and rod to normal idle positions during"v the return stroke of the main drive shaft. The levers 615 1/2 and rod 005, therefore, constitute combined transfer resetting and locking .mechanism.

The drive shaft 200 on its return stroke, first retires the drive members 310 to directly register on the counters 490, the amount set up on the keyboard. In case the capacity of one of the counters is exceeded in thisoperation, its cam 411 Will wipe past the free end of its trigger 612 to release the transfer device .to the action of the spring 680. Should the transfer devices locked against any movement, at this time, the'trlggers would spring back to effective positions beneath the front rocker arms and prevent the carry, On the other hand, in the resent construction, if a carry was permitted during the engagement of the rendered ineffective or swallowed if an amount was also being registered on? the counter onto which the carry was to be made.

It is customary, therefore, to permit a slight preliminary throw Of'llhfi transfer device sullicient to block the tripped tri er 612 against return, but not sufficient to e ect a carryin operation in order that thecarry shall not we lost. ThisI arrange for my invention its-follows: i

The drive shaft 200 thie' end of forward stroke has rocked the-trhnsfer resetting mechanism and transferdevices to the limit of their effective movement inpnedirection, the keepers 615 1/2 of the esetting levers swinging some distance below the locking shoulders 616" of the latches (Fig. 52) extensions of which remain in cont-act with the keepers to retain the latches and resetting levers in engagement. At the beginning of its return stroke, the shaft 200 shifts the rod 303 baekwardly in the slots 6153/4 of the actuating links 615 3/4, the trip rod also idly traverses the slots in pro s 31.) and links 321, withoutrestoring, said links. As the trip rod recedes from the forward end walls of the actuating links 615' 3/4, it frees them to the action ofthe springs 38% to permit the latter to rock the resettinglevers 01.") 1/2 rcarwardly and lift the resetting rod 605 awayfrom the lower position by ends of the slots in the connecting links 613, until the keepers 615 1/2 strike shoulders 616 on the latches which arrest the resetting rod before it haspassed out of locking position relatively to the transfer devices. Incidentally the resetting levers partiallyretract the actuating links, and the forward edges of the latches 616 overlapthe rear ends of the slots 615 3/4 thereinl The resetting rod 605, by this operation permits the carrying springs 680 to tilt the forward arms of the, rockers 610 downwardly until their lugs 610' rest on the gers, at which tame, the lower ends of the slots 613lie'below the resetting rod 605. When a' trigger is tripped on the return stroke, the spring 680 rocks the rear arm of the transfer device upwardly until the latter is arrested by the contact of the lowerv end.

of theslot in theconnecting link; 613 with the rod 605, and the lug 610 on the forward arms of the rocker 610 simultaneously shifts downwardly behind the projection 635 on the trigger to hold the latter in idle position.

The transfer device is maintainedin this rod 605 as the trip rod 303 continues to retrace its path of travel. during the return stroke of the drive shaft 200, untilthe retirement of the drivemembers 310, whereupon the drive shaft, through the trip' rod 303 lifts the props319 to disengage the counters and drix e' or the rollers 636 thereon which traverse the slots in the actuating links 615 3/4, now strikethe forward edges of the latches 616 which overlap the rear ends of the slots 615 3/4 to force-their shoulders 616"oif the keepers 615 1/2? and free the resetting; mechanism to the action of its springs 384, which members. The trip rodthen restore the transfer resetting mecha-" nism to normal idle position where it is held by the engagement ofthe kee rs 615 1/2 with Shouldersl616 of the latch ea 616.

a The transfer devices which may have been arrested in tripped position'are free to operate under practically the full tension of their springs 680 as the resetting rod605 returns. to normalposition, and automaticall efi'ect snap carries with great speed. The ull and dotpt ed line positions of the handle 210 1/2 1Il 4g.

the drive shaft rocks from the time when "the latches 616 are displaced, tn the end of the 2o return stroke. r .In case the time interval between the ="release of the lutclies 616 near the close of one operation of the machine,

of the succeeding operation of the machine, is not sulliciently longto complete the carrying action, as might readily happen in rapidly successiverepeat operations, for instance, it. is plain that thecarrying operations may extend throughout nearly. the entire time of the succeeding forwanfstroke,

3 ind cate the distance through which and the beginning I6 oriu'ntil the transfer resetting mechanism is actuated. ,This gives a very much longertlme within'which a carry may take place than heretofore, and practically prevents the possibility of interrupting or cutting off thecar.
